1 0 (ZZZ whom it may concern.

Be it known that LEDWARD H. KRUsn, a citizen of the United States of America, and resident of Fort lVayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Switch Boxes, of which the following is a specification.

This invention relates to improvements in switch boxes of that type used for enclosing electrical switches and adapted to be mounted in a partition or wall of a building, and especially that type of box intended to be mounted so that its front will be flush with the surface of the wall in which it is mounted.

In installing boxes of this type, during the construction of buildings, it is customary to secure the box in the wall by means of brackets so that its front will project suffi ciently as to be flush with the plastering that is subsequently applied to the wall. Also, when the box is installed after the wall has been completed with the plastering in place, it is necessary that the brackets be so placed in connection with the box that the box will be let into the wall to the extent that its front is flush with the plaster.

The object of the invention is to provide a switch box with brackets so constructed that they may be adjustably positioned on the box so that the front thereof will be in the plane of the surface of the plastering when installed either before or after the plastering has been applied. A further object is to so construct the adjustable brackets and their securing means that they may be readily adjusted by manipulation with the hands and without the necessity of tools or screws so that economy of installation is attained.

The objects of the invention are accomplished by the construction illustrated in the accompanying drawings in which:

Fig. 1 is a perspective view of a switch box embodying the invention;

Fig. 2 is a side elevation of the switch box shown broken away and including the adjustable brackets; and

Fig. 3 is a detail view showing a cross section of the upper part of Fig. 2 on the line w, thereof.

Similar characters of reference indicate corresponding parts throughout the several views and referring now to the same:

Serial No. 449,716.

1 is a switch box of usual form and construction, and 2 are brackets adjustably sethe box forengaging eachbracket and holding it in adjusted positions.

The outer end of each bracket projects at right angles from the top or bottom of the box to which it is secured and is adapted to be fastened in the usual manner to the wall of the building by means of screws or nails, and each bracket has a pair of arms 4 arranged in parallel relation with each other and each of which lies flat against the top or bottom of the box, as the case may be. Each arm has also a series of indentations or perforations 5, and its rear end 6 is upturned so as to form a stop.

The clip 3 is secured at its middle portion to the box in position between the arms of the bracket by means of rivets 7 or by spotwelding, and the outer ends of the clip are offset so as to extend over and thus secure the corresponding arms of the bracket, there being an indentation 8 made in each end of the clip that forms a corresponding projection 9 adapted to engage the perforations 5 in the corresponding arms of the bracket selectively as the bracket is shifted from one position to another. The stops 6 on the ends of the arms, by coming into contact with the clips, prevent dismemberment of the brackets.

By thus constructing the invention the brackets may be shifted to such positions on the box as may be required to install the box properly in the wall, and this is readily accomplished without the use of tools or screws that ordinarily are required and sometimes renders the box useless because of the loss of parts.

lVhat I claim is 1. In a device of the class described, a box; brackets for the top and bottom of the box, each bracket having a pair of parallel arms; and a clip for each bracket secured at its middle portion fixedly to the box between the arms of the bracket, and each end of the clip having an offset extending over and securing the corresponding arm of the bracket adjustably on the box.

2. In a device of the class described, a box; a spring clip on the top and bottom of the box, each clip being fixedly secured thereto; and a bracket for the top and bottom of the box, each bracket having parallel arms adjustably secured by the correspond ing clip to the box.

3. In a device of the class described, a box; a bracket for the top and bottom of the box, each bracket having perforated parallel arms; and a spring clip for each bracket having fixed relation with the boX at its middle portion and engaging relation at its ends with the corresponding arms of the bracket, there being a projection on the clip adapted to engage the perforations and hold the bracket in adjustable positions.

4;. In a device of the class described, a box; a spring clip at the top and bottom of the box, each clip being permanently secured at its middle thereto; and a bracket in adjustable relation'with each clip having parallel arms engaged respectively by the ends of the corresponding clip, there being a stop at each end of said arms adapted to limit the movement of the corresponding bracket relative to the box in both directions by engagement with the corresponding clip.

In testimony whereof I atfix my signature, in presence of two witnesses.
